Answer:
The domain is (-infinity, -3) ∪ (-3, 3) ∪ (3, infinity)
Step-by-step explanation:
This function is defined for all t such that the denominatory t^2 - 9 is not zero (0). Purposely setting t^2 - 9 = 0, we find that t = 3 or t = -3.
This function defined everywhere except at {-3, 3}.
x=-2.8
Its 4 because 2+2 is 4 and then you're subtracting 2 and then adding 2 again so its 4

a1=-2
r=-2
